We need to translate Russian news post into natural English, format per guidelines.

First line: short headline under 90 chars, no markdown, no '#'.

Then blank line, then body paragraphs short (2-3 sentences each), separated by blank lines.

Wrap few genuinely important facts (key numbers, percentages, drug/company/gene names, dates) in double asterisks . At most 4-5 per post, never a whole sentence.

Wrap study/journal citations and publication references in single underscores _ (e.g., Nature Medicine, August 26, 2024? Actually they gave date: published August 26, 2024? The Russian says "опубликованной 26 августа". No year given but likely 2024? We'll keep as given: Nature Medicine, August 26 maybe include year if known? We'll just follow: Nature Medicine, August 26.

We need to preserve facts: recombinant shingles vaccine vs live attenuated vaccine; 7-year follow-up; older than 60 US; cohorts: April-Sept 2017 (live vaccine) and same months 2018 (recombinant). Each cohort 36,460 people. In 2017 cohort 98.6% got live vaccine; in 2018 cohort 93.5% got recombinant. Over 7 years, participants in later cohort spent 9% more time free of at least one of these diagnoses (ischemic heart disease, ischemic stroke, heart failure). Difference persisted separately for ischemic heart disease and heart failure. In year before vaccination, groups had same rates of those diagnoses and preventive care. Calendar period check: tetanus-diphtheria-pertussis vaccine recipients showed similar time free of CV diagnosis. Authors previously used vaccine switch as natural experiment for dementia study; now applied to CV diagnoses. Authors consider AS01 adjuvant component of recombinant vaccine as possible link between immune response and vascular state. In another vaccine study with AS01 in healthy adults, monocyte subtypes changed; some DNA methylation changes persisted up to six months. Authors suggest similar immune changes may be linked to vascular state.

We need to bold key numbers: maybe 7 years, 9%, 36,460, 98.6%, 93.5%, AS01, etc. But limit to 4-5 total bolded items. Choose most important: 7 years, 9%, 36,460, 98.6%, 93.5%? That's 5. Could also bold AS01 but that would be 6. So maybe bold: 7 years, 9%, 36,460, 98.6%, 93.5%. That's 5.

We must not bold whole sentences. So embed bold within sentences.

Citation: Nature Medicine, August 26 (maybe include year if known but not given). We'll just put Nature Medicine, August 26.

Now format: Headline line, blank line, then paragraphs.

Paragraph 1: summary of study and cohorts.

Paragraph 2: results (9% more time free, etc.)

Paragraph 3: details about cohorts matching, baseline similarity, calendar period check.

Paragraph 4: link to previous dementia work, AS01 adjuvant, monocyte changes.

Make sure each paragraph 2-3 sentences.

Let's craft.

Headline: "Recombinant shingles vaccine linked to longer cardiovascular disease‑free period in older adults"

Extropianism: The Philosophical Roots of Modern Transhumanism

Extropianism became the practical and philosophical foundation from which modern transhumanism grew in the late 20th century. The term extropy, coined by philosopher Max More in 1988, was conceived as a metaphorical opposite of entropy — a measure of intellect, functional order, vital energy, and a system’s drive for continual improvement.

While classical physics predicts the inevitable decline of systems, extropianism proposes a reverse process: the constant increase of complex order in the human organism and mind through science. This movement transformed abstract dreams of immortality into a concrete technological vector focused on cryonics, nanotechnology, mind uploading, and exponential growth of computing power.

The organizational center of the philosophy was the Institute of Extropy (ExI), founded by Max More and Tom Bell, together with the journal Extropy: The Journal of Transhumanist Thought, which created the first cohesive network of futurists.

In the 1990s, heated debates took place via the institute’s mailing list, involving key figures of the forthcoming technological revolution: nanotech advocate Eric Drexler, B‑money creator Wei Dai, Bitcoin developer Hal Finney, WikiLeaks founder Julian Assange, and philosopher Nick Bostrom.

By 2006, ExI’s board announced its closure with the statement

Wrap study/journal citations and publication references in single underscores (e.g., Nature Aging, July 2026).

We need to preserve all facts, numbers, names, citations exactly. No added commentary.

We need to identify important facts: dates: 1988 (term introduced), 1990s (discussions), 2006 (board announced closing). Also maybe names: Max More, Tom Bell, Institute of Extropy (ExI), journal Extropy: The Journal of Transhumanist Thought, Eric Drexler, Wei Dai, Hal Finney, Julian Assange, Nick Bostrom. Also maybe "cryonics", "nanotechnologies", "mind uploading", "exponential growth of computing power". But we need to limit double asterisks to at most 4-5. Choose the most important: 1988, 2006, maybe Max More, Institute of Extropy (ExI), journal Extropy: The Journal of Transhumanist Thought. But those are names not numbers; still can be wrapped? The rule says "key numbers, percentages, drug/company/gene names, dates". So we can wrap dates and maybe company names? It says drug/company/gene names. So we can wrap company/institute names? Possibly yes as they are organization names. But better to stick to dates and maybe the term "ExI". However we need at most 4-5 double asterisks. Let's pick: 1988, 2006, Max More, Institute of Extropy (ExI), Extropy: The Journal of Transhumanist Thought. That's 5.

But we also need to wrap study/journal citations in single underscores. There's no explicit citation like a journal article; but we have the journal Extropy: The Journal of Transhumanist Thought. That is a publication reference; we could wrap it in single underscores as per rule: Extropy: The Journal of Transhumanist Thought. However we already used double asterisks for that name; we cannot double wrap? The rule says wrap study/journal citations and publication references in single underscores. So we should use single underscores for that journal name, not double asterisks. So we need to decide: we have limited double asterisks for key numbers etc. For journal citation we use single underscores. So we could double asterisk the dates and maybe Max More and Institute of Extropy (ExI). Then single underscore the journal name.

Let's choose double asterisks: 1988, 2006, Max More, Institute of Extropy (ExI). That's 4.

Single underscore: Extropy: The Journal of Transhumanist Thought.

Now we need to ensure we preserve all facts. Let's translate the Russian paragraph into English, then split into short paragraphs (2-3 sentences each). We'll need to embed the formatting.

Let's draft translation:

Wrap few genuinely important facts — key numbers, percentages, drug/company/gene names, dates — in double asterisks . At most 4-5 per post, never a whole sentence.

Wrap study/journal citations and publication references in single underscores _ (e.g., Nature Aging, July 2026). There's no citation in the text, but maybe we can add none.

We must preserve all facts, numbers, names, citations exactly. No added commentary.

Let's extract facts:

- LatchBio presented BioSecBench-Function on August 27.
- BioSecBench-Function is a set of 111 testable tasks about properties of viruses, bacteria, toxins.
- Agent receives genetic sequence, molecular structure, or experiment results, selects analysis and formulates conclusion, compared to known answer.
- Among 22 combinations of language models and agent programs, best configuration performed 50.3% of tasks, excluding refusals due to biosafety rules; counting refusals as errors, another configuration led with 44.1%.
- When surveillance system detects a new pathogen, researchers need to understand its properties and choose an experiment to test a hypothesis. Decision depends on what measurements considered sufficient and how to match results. BioSecBench-Function moves this work into testable tasks.
- In each task, agent reads data, selects needed analysis and formulates conclusion; compared to known answer. Test evaluates how system links data, selected analysis, and final conclusion.
- Two numbers answer different questions. 50.3% considered among attempts where system did not refuse to perform task per biosafety rules; 44.1% obtained when such refusals counted as errors.
- Authors separate ability to reason from data from reaction of protective filters, therefore counting rule changes leader.
- Answer trajectories show what hides behind percentages. In one task, two types of experiment gave divergent results; next step should have been a confirmatory experiment. Almost no agent suggested it.
- In another task, measurement error for different variants differed by more than a hundredfold. Agents with a single numeric threshold took noise for drug resistance.
- In such tasks, agent must match data, assess its sufficiency for conclusion, and in conflict assign next experiment. BioSecBench-Function checks this decision together with final answer.

We need to wrap key numbers, percentages, drug/company/gene names, dates in double asterisks. At most 4-5 per post.

Key numbers/dates: August 27 (date), 111 tasks, 22 combinations, 50.3%, 44.1%, two types of experiment, measurement error > hundredfold.

We need to be selective: maybe 4-5 double asterisks.

Potential double asterisks: August 27, 111, 22, 50.3%, 44.1%, hundredfold. That's 6. Need at most 5. Could combine some.

We could do: August 27, 111 tasks, 22 combinations, 50.3%, 44.1%. That's 5. The hundredfold maybe not needed as double asterisk; we can leave it plain.

Also need to wrap study/journal citations in single underscores; none present, so none.

Now format: headline line, blank line, then paragraphs.…

We need to translate Russian news post into natural English, format with headline line (<90 chars), blank line, then body paragraphs (2-3 sentences each) separated by blank lines. Wrap few genuinely important facts (key numbers, percentages, drug/company/gene names, dates) in double asterisks. At most 4-5 per post. Wrap study/journal citations and publication references in single underscores.

We need to preserve all facts, numbers, names, citations exactly. No added commentary. No source link.

We need to identify important facts: Outer Bio presented Yuna on August 24 (date). Yuna system for four-week experiments on living human skin experiments. 8-millimeter full-thickness biopsy. 3D-printed porous insert. Study 2020 other model preserved integrity up to nine days. Authors observed biopsies from 19 donors up to four weeks and performed 118 replicates. Early adaptation period; gene activity profiles weeks 1-4 closer to each other than fresh skin. Next experiment: biopsies of four donors treated three weeks with immune signaling molecules IL-17A and IL-22. Inflammatory changes persisted: gene activity related to inflammation and skin barrier changed; inflammatory proteins secreted into medium. Tofacitinib, a drug that blocks one immune signaling pathway, attenuated part of these changes. Separate experiment: skin of three donors aged 58–74 treated three weeks with dasatinib alone or combined with quercetin. At end, authors registered reduced levels of IL-6 and MMP1. Calculated by SenSkin gene activity — a marker of skin cellular aging — and authors' chronic inflammation signature also decreased. Four-week window allows separating early tissue adaptation from changes caused by long treatment. In it one can observe processes in human skin that unfold over weeks, not only first days of culture.

We need to wrap key numbers, percentages, drug/company/gene names, dates in double asterisks. At most 4-5 per post. So we need to select maybe 4-5 important facts: date August 24, 8‑millimeter biopsy, 19 donors, 118 replicates, four‑week window, maybe IL-17A/IL-22, tofacitinib, dasatinib+quercetin, SenSkin, etc. But we must limit to 4-5 double asterisks total. So we need to be selective: maybe highlight date, 8‑mm biopsy, 19 donors, 118 replicates, four‑week window. Or maybe include drug names as important facts? The instruction: "Wrap the few genuinely important facts — key numbers, percentages, drug/company/gene names, dates — in double asterisks. Be selective: at most 4-5 per post, never a whole sentence." So we can include drug names as important facts. But we need to limit total double asterisk occurrences to 4-5. Let's decide to include: August 24, 8‑millimeter, 19 donors, 118 replicates, four‑week. That's 5. Good.

We must not double asterisk other numbers like 58–74 years, IL-6, MMP1, etc. So we will leave those plain.

Now citations: we have a 2020 study (other model). We need to wrap study/journal citations and publication references in single underscores. The text mentions "В исследовании 2020 года другая модель человеческих кожных эксплантатов сохраняла целостность ткани до девяти дней в описанных авторами условиях." No journal name given. So we can just put 2020 study? But we need to preserve citation exactly; we don't have a journal name. Could use 2020 study as placeholder. However instruction: "Wrap study/journal citations and publication references in single underscores (e.g. Nature Aging, July 2026)." So we need to wrap whatever citation appears. Since there is no explicit journal, we can wrap the phrase "2020 study" in underscores. Or maybe "В исследовании 2020 года" -> we can wrap "2020 study". Let's do 2020 study.…

FDA increasingly relies on single studies for drug approvals

In 2024, the US FDA approved 69.4% of new drugs based on the results of a single study. An article published August 26 examined all FDA approvals from 2016 to 2024 and the 6,763 related studies. Over that period, the average number of studies supporting each approval fell from 3.41 to 1.39.

The authors extracted from FDA packages the studies the agency directly relied on and those cited in the decision rationale. In February, FDA guidance proposed treating one pivotal study as the usual basis for approval. In the authors’ data, a single study became the most common approval basis already in 2017; in 2024, only 5.6% of approved drugs relied on three or more studies.

The historical preference for two studies is tied to reproducibility: “Requiring at least two studies for approval reflects the core scientific principle of reproducibility.” The evidentiary package also includes trial design details—what treatment was compared to, how participants were allocated, and

Wrap study/journal citations and publication references in single underscores _ (e.g., Nature Aging, July 2026).

We have a preprint by Zongmin Lu dated August 26. So date is August 26 (year unspecified). We'll put date in double asterisks? It's a key fact. Also numbers: average correlation 0.555, 0.681, ceilings 0.745, 0.825, consistency 0.897, 70–90%, 63%, 18%, accuracy rose from 0.175 to 0.235, etc. Need to select at most 4-5 double-asterisk facts. Choose the most important: date, average correlations, ceilings, consistency, maybe the improvement in accuracy. That's 5.

We must not wrap whole sentences, only the facts inside double asterisks. So embed them within sentences.

Also need to wrap study/journal citations in single underscores. There's no explicit journal citation; it's a preprint. Could treat the preprint as a citation? Probably not needed. But we could wrap the preprint reference: Preprint by Zongmin Lu, August 26? However rule says wrap study/journal citations and publication references in single underscores. Since it's a preprint, we can treat as a publication reference: Preprint, August 26. We'll do that.

We need to ensure we don't exceed 4-5 double asterisks. Let's pick:

- August 26 (date)
- 0.555 and 0.681 (two numbers) maybe combine? But each number counts as a fact. Could combine as "average correlations of 0.555 and 0.681". That's two double asterisks.
- 0.745 and 0.825 (ceilings) two more.
- 0.897 (consistency) one more.
- 70–90% (percentage) one more.
- 63% and 18% maybe two more but that would exceed.

We need at most 4-5 total. Let's aim for 5 double asterisks.

Pick: date, average correlations (maybe combine as one fact? but two numbers). Could treat the pair as one fact? Might be risky. Better to select: date, average correlation 0.555, ceiling 0.745, consistency 0.897, improvement in accuracy from 0.175 to 0.235 (two numbers though). Hmm.

We could embed multiple numbers within same double asterisks? Eg 0.555–0.681 as a range counts as one fact. Similarly 0.745–0.825 as another. Then we have date, those two ranges, consistency, maybe accuracy improvement. That's 5.

Let's do:

- August 26
- 0.555–0.681 (average correlations)
- 0.745–0.825 (ceilings)
- 0.897 (consistency)
- 0.175 → 0.235 (accuracy improvement)

That's 5 double asterisks.

Now we need to wrap study/journal citation in single underscores. We'll do Preprint, August 26 maybe but date already used. Could do Preprint by Zongmin Lu . We'll put that somewhere.

Now produce headline under 90 chars. Something like: "Study Sets Precision Limit for Single‑Score Protein Variant Models". Count characters: Let's count: "Study Sets Precision Limit for Single‑Score Protein Variant Models". That's about 61. Good.

Did DARPA Develop Injectable Mind‑Control Tech? Spoiler: No

The N3 (Next‑Generation Nonsurgical Neurotechnology) program was launched in 2018 with the goal of creating a non‑ or minimally invasive neurointerface capable of reading and writing neural signals in under 50 ms, providing at least 10 degrees of freedom, and achieving 95 % of the fidelity of implanted electrodes. The effort was divided into external helmets (TA1) and minimally invasive delivery routes (TA2) such as injections, swallowing, or nasal administration.

The most ambitious TA2 track was BrainSTORMS from Battelle, funded with $12.9 million by DoD, which proposed injecting magnetoelectric nanoparticles into the bloodstream, steering them with external magnets to target brain areas, and converting neuronal electric activity into magnetic signals for an external helmet. Rice University’s MOANA project received $13.8 million to use viral vectors to make brain cells optically readable and magnetically stimulable, reaching phase III in May 2024.

To date, the only human‑tested system is Carnegie‑Mellon’s SharpFocus, which relies on external electrodes and focused electric fields. A March 2026 study on BrainSTORMS traces concluded that reverse reading of neural activity via nanoparticles remains “predominantly theoretical,” and the Johns Hopkins Lab, end 2024 admitted that picking up signals through the scalp and skull is still

Wrap study/journal citations and publication references in single underscores _ (e.g., Nature Machine Intelligence, August 28, 2026? Actually article date: 28 августа в Nature Machine Intelligence вышла статья. So we need to wrap that citation: Nature Machine Intelligence, August 28, 2026? The year not given; article presumably 2024? But we just keep as given: "28 августа в Nature Machine Intelligence вышла статья". We'll wrap the journal name and date: Nature Machine Intelligence, August 28.

We need to preserve facts, numbers, names, citations exactly.

Important facts: GOLLuM method, date Aug 28, article in Nature Machine Intelligence, 23 tasks, budget 50 experiments, GOLLuM average found 36.3% of conditions in top 5% results; standard Bayesian optimization 29.7%; in Buchwald-Hartwig reactions test, proportion of top 5% conditions rose from 24% (language model without fine-tuning) to 43% after joint training with GP. Also mention that they started with ten conditions below median. Also mention they released code, data, configs.

We need to select at most 4-5 double asterisk facts. Choose: August 28, Nature Machine Intelligence, 23 tasks, 50 experiments, 36.3%, 29.7%, 24%, 43%. That's many; need limit to 4-5. We'll pick the most important: date, journal, 23 tasks, 50 experiments, 36.3% vs 29.7%, maybe also the Buchwald-Hartwig improvement 24% to 43%. That's more than 5. Let's think: we need at most 4-5 double asterisk facts. Could combine some: maybe we can embed multiple numbers in one double asterisk? The rule: wrap the few genuinely important facts — key numbers, percentages, drug/company/gene names, dates — in double asterisks. Be selective: at most 4-5 per post, never a whole sentence.

Thus we need to choose up to 5 items to bold. Let's pick: August 28, Nature Machine Intelligence, 23 tasks, 50 experiments, 36.3% (maybe also mention 29.7% but that would be 6). Could we combine 36.3% and 29.7% into one double asterisk? Like "36.3% vs 29.7%"? That's still one fact (comparison). That counts as one. Then we also need Buchwald-Hartwig improvement maybe as another fact: "24% → 43%". That would be total: date, journal, 23 tasks, 50 experiments, 36.3% vs 29.7%, 24% → 43% = 6. Too many.

We could drop one: maybe we don't need to bold the date if we can put date in underscores? No, date is not a citation; it's a fact. Could we embed date inside the underscores with journal? Eg Nature Machine Intelligence, August 28 includes date, but that's underscores not double asterisk. So date can be inside underscores, not counting toward double asterisk limit. Good! So we can put the date inside the single underscores with journal citation. Then we have double asterisks for: 23 tasks, 50 experiments, 36.3% vs 29.7%, 24% → 43%. That's 4 double asterisks. Good.

Now we need to wrap study/journal citations and publication references in single underscores. So we will have Nature Machine Intelligence, August 28 (maybe include year if known but not given). We'll keep as given.

Intestinal ACP7 secretion extends lifespan in C. elegans

Researchers artificially boosted ACP7 production in the intestine of C. elegans and found that lifespan increased only when the enzyme was secreted from gut cells.

The median lifespan rose by 10%, and the age at which 10 % of worms survived increased by 22%; the study appeared on 27 August in Cell Reports.

Using TurboID labeling in the endoplasmic reticulum, the team performed mass spectrometry on worms aged 3, 8, and 13 days, identifying 238 extracellular or secreted proteins, of which 191 changed with age and 89 have human homologs.

Four candidate proteins were tagged with fluorescent markers and all were detected outside the intestine and in coelomocytes; ACP7 levels were shown to rise with the worms’ age.

Removing the 21‑amino‑acid signal peptide kept ACP7 inside the intestine and abolished its life‑extending effect, while the ACP7‑7A variant with seven substitutions in the metal‑binding domain retained secretion but lost phosphatase activity and failed to prolong lifespan.

Human ACP7 was secreted in cell culture and demonstrated phosphatase activity on an artificial substrate; a computational screen pointed to 28 extracellular proteins that could be dephosphorylated by worm ACP7, providing targets for future work linking the enzyme’s activity to longevity.

We need to select at most 4-5 double-asterisk facts. Choose maybe: 27 August, 6,053 participants, 443 centenarians, 3,219 controls, 2,391 Alzheimer's patients? That's 5. But we need to be selective; maybe we can include date and total participants, and numbers of groups. Could also include gene names: DRB1*04, DRB1*01:01, DRB1*15:01. Those are also important facts. But we have limit 4-5 double asterisks total. We need to decide which to highlight.

Probably highlight: 27 August, 6,053 participants, 443 centenarians, DRB1*04, DRB1*01:01? But also need DRB1*15:01 maybe not.

Alternatively we could highlight numbers and gene names combined: e.g., DRB1*04, DRB1*01:01, DRB1*15:01 as three, plus date and total participants = 5.

Let's decide: double asterisk for: 27 August, 6,053 participants, DRB1*04, DRB1*01:01, DRB1*15:01. That's 5.

Now single underscores for study/journal citations and publication references. The text mentions a preprint published 27 August. No journal name given. Could be something like bioRxiv? Not given. It says "В препринте, опубликованном 27 августа". So we can wrap the preprint reference: preprint, published 27 August. But we need to keep citation exactly; we don't have journal name.

Paragraph 2: talk about grouping 24,651 DNA variants into seven sets, three overlapping previous signals.

Paragraph 3: explain HLA-II function, variability, inheritance.

Paragraph 4: talk about Hap-B associated with DRB1*04, more common in controls and centenarians, linked to lower Braak tau stage, persists after accounting for amyloid.

Paragraph 5: Hap-R associated with DRB1*01:01 more frequent in patients, less in centenarians and controls.

Paragraph 6: Hap-Y associated with DRB1*15:01 linked to greater HLA-II staining area in microglia, reflecting microglial immune state; tau pathology assessed by another scale.

Adaptyv Bio Links Lab Validation to Rosalind Workbench via API

Adaptyv Bio announced on 29 August that it has linked its lab validation to Rosalind Workbench OpenAI via the Adaptyv API; experimental data will flow into the next round of protein design.
On 28 August, OpenAI launched Rosalind Workbench as a workspace for biological research, where a researcher can pose a question, run analysis, and draft an experiment plan.
In an example, Workbench helped select nanobody candidates — small proteins that bind a given molecule — and plan and evaluate the cost of binding tests for five nanobodies. The new integration adds a laboratory step to this workflow. Through the Adaptyv API, the protein sequence (the amino‑acid order) is sent to the experiment; the lab can test whether the produced protein binds the target molecule and return the results via the platform or API.
Adaptyv Bio notes that the physical‑experiment data feed directly into the next design round, so the subsequent protein‑sequence choice is based on the binding‑test result.

We need to translate Russian news post into English, format per rules.

First line: short headline under 90 chars, no markdown, no '#'.

Then blank line, then body split into short paragraphs (2-3 sentences each), separated by blank lines.

Wrap few genuinely important facts — key numbers, percentages, drug/company/gene names, dates — in double asterisks . At most 4-5 per post, never a whole sentence.

Wrap study/journal citations and publication references in single underscores _ (e.g., Nature Aging, July 2026).

We need to preserve all facts, numbers, names, citations exactly.

Let's extract facts:

- Date: 28 августа (August 28) in Cell Reports (re-analysis of data). So date: August 28 (year not given? The article presumably 2024? Not given. We'll keep "August 28" as given.

- Data: single-cell brain data of male mice.

- After QC: 12,310 cells remained.

- Pairs of young and old mice with surgically joined circulations – heterochronic parabiosis.

- One-cell atlas of such pairs in 2022 collected by Robert Palovich with coauthors; Palovich also in current team.

- Mice of same age served as control.

- Authors identified eight microglial states.

- In six activated states, 75 genes changed similarly in at least five of them.

- Forty of these 75 genes entered the common age shift in all four brain regions.

- Common program manifested in all regions, but each had its own shifts.

- In young mice with old partners, gene activity in cerebellum and cortex changed in same direction as normal aging, albeit weaker.

- Under both influences, most changes seen in cerebellum.

- In old mice with young partners, in cerebellum 41 genes changed activity opposite to age changes; in cortex and hippocampus 25 each; in striatum three.

We need to wrap key numbers, percentages, drug/company/gene names, dates in . At most 4-5 per post.

Select maybe: 12,310 cells, August 28, 75 genes, 40 genes, 41 genes, 25 genes, three genes? That's many. Need max 4-5. Choose most important: total cells, date, number of genes commonly shifted (40), number of opposite changes in cerebellum (41), maybe number of opposite changes in cortex/hippocampus (25). That's 5.

We must not wrap whole sentences. So embed within sentences.

Citations: we have Cell Reports (journal) and the 2022 one-cell atlas by Robert Palovich et al. We need to wrap study/journal citations and publication references in single underscores _. So we should put Cell Reports and maybe 2022 one-cell atlas? The instruction: wrap study/journal citations and publication references in single underscores (e.g., Nature Aging, July 2026). So we should put the journal name in underscores. Also maybe the 2022 atlas reference? Could be considered a publication reference; we can put Robert Palovich et al., 2022 or similar. But we need to preserve exact names. The Russian text: "Одно-клеточный атлас таких пар в 2022 году собрал Роберт Палович с соавторами ; Палович вошёл и в нынешнюю команду." So we can cite as Robert Palovich et al., 2022 (or 2022 one-cell atlas by Robert Palovich et al.). We'll put the citation in underscores.

We need to ensure we don't add extra commentary.

Now format: Headline line, blank line, then paragraphs.

Paragraphs 2-3 sentences each.

Let's craft:

Headline: "Heterochronic parabiosis reshapes microglial gene activity across mouse brain regions"

Check length: count characters: "Heterochronic parabiosis reshapes microglial gene activity across mouse brain regions" Let's count: H(1) ... I'll approximate less than 90. It's fine.

Blank line.

Paragraph 1: maybe 2-3 sentences about study date, data, QC.…

TranslAGE Defends Biomarker Responsiveness Amid Critique

TranslAGE brought together 51 studies in which human participants had blood drawn before and after an intervention. In every dataset the authors uniformly calculated 16 epigenetic clocks — algorithms that estimate age‑related changes from DNA chemical marks.

On August 30 Raghav Segal, the first author of TranslAGE, replied to criticism from biogerontologist Matt Kaeberlein. Kaeberlein’s objection is whether a shift in such a marker can be used to judge the impact of a drug, diet, or exercise regimen on a person.

The authors harmonized the data from those 51 studies and applied a single panel of the 16 clocks to each dataset, making it possible to compare marker shifts across different groups, time periods, and interventions. Segal phrases the article’s core question as: “Do these biomarkers respond to interventions in the expected direction, how strongly, and how consistently?”

He describes the route to a clinically useful marker in three words: prognostic → responsive → surrogate. Prognostic ties the marker to future disease, function, or mortality; responsiveness shows its shift after an intervention; surrogacy would let that shift predict a patient‑relevant outcome. In the paper responsiveness is presented as a step toward a surrogate marker, which TranslAGE tests by examining how the clocks react to presumed anti‑aging interventions. Kaeberlein’s follow‑up question is whether that shift can be linked to the concrete outcome of a specific intervention in an individual.

NAD+ and NADPH levels in muscle correlate with function more than with age

On 28 August the authors of a preprint measured six metabolism‑related compounds in muscle biopsies from 137 men aged 20–93 years. Total NAD(H) and NADP(H) pools showed no significant age‑related change.

After adjusting for age, NAD+ remained associated with walking speed, leg power, muscle mass and mitochondrial count; NADPH retained links to walking, leg power, muscle mass, mitochondrial respiration and mitochondrial number. NAD+ fuels energy‑producing reactions, while NADPH supports biosynthesis and glutathione regeneration.

Both glutathione forms rose with age in parallel, keeping their ratio stable. To test whether the NAD(P) links reflected mitochondrial quantity or respiratory capacity, the authors used citrate‑synthase activity as a mitochondrial‑number marker. NAD+ and NADPH correlated with both citrate‑synthase activity and maximal respiration; when respiration was normalized to citrate‑synthase activity, the associations disappeared, indicating mitochondrial number as the proximate explanation.

The authors note that 2022 study data had shown lower NAD+ in older adults, especially those with poorer physical performance, whereas trained older adults approached youthful levels. A May analysis of NAD+ in whole blood across seven human cohorts also found little age‑related change. They conclude that NAD(P) exchange metrics better reflect preserved muscle health than aging, and that NAD‑modulating interventions should be evaluated by corresponding tissue‑specific functional outcomes.

Jaba Tkemaladze proposes centriole inheritance as a marker of aging in renewing tissues

On 28 August he posted a preprint on the Research Square platform outlining the “centriole counter” hypothesis.

In tissues that renew through repeated divisions, a cell lineage can retain changes in the centriole from one division to the next. In his earlier framework of four hallmarks of cellular age, Tkemaladze placed centrioles alongside telomeres and mitochondria. The current preprint narrows the focus to tissues that constantly replenish themselves with new cells.

A renewing tissue simultaneously replaces specialized cells and maintains a reserve of cells that can divide again. During division, the two daughter cells may receive

Retro expands Phase I trial of RTR242 to 108 volunteers in Australia

Retro will add two high‑dose cohorts and increase its Phase I study of RTR242 to 108 participants in Australia. The trial enrolls healthy adults aged 18–65 years. This expansion follows the initial dosing that began earlier this year.

The company is adding 32 participants and two new dose‑escalation groups to better define the dose for further clinical development. These groups will help Retro select the optimal dose for subsequent trials. The move aims to pinpoint a tolerable level that can be taken forward.

On August 26, CEO Joe Betts‑Lacqua told Business Insider that the study would grow from 76 to 108 volunteers. In May Retro announced the first human administration of RTR242. Since that start, the company has been expanding enrollment and raising doses.

Betts‑Lacqua explained that early tolerability testing has not yet revealed an upper dose limit, so the team must find a level participants can tolerate and carry into later studies. He said, “This is for us in some sense both a curse and a blessing: because of this it’s a bit harder to assess the moment when we can say: ‘hurray, the drug works’.”

Retro describes RTR242 as a small‑molecule compound that enhances autophagy — the process whereby a cell delivers damaged proteins and cellular components to lysosomes for breakdown. In lysosomes, the acidic interior degrades this cargo into reusable building blocks. The company expects RTR242 to restore lysosomal acidity and make this recycling more efficient.

Full Robbins, a biochemist at the University of Minnesota, called lysosomes an intriguing target for intervention. With the additional 32 participants, Retro widens the dose range from which it will choose the level for further development of RTR242.

We need to preserve all facts, numbers, names, citations exactly.

Let's extract facts:

- João Pedro de Magalhães (note spelling: "Жуан Педру де Магальяйнш" -> "João Pedro de Magalhães").
- He hypothesized that cancer protection may limit regeneration.
- On August 27 he hypothesized: developmental transitions could limit tissue restoration to reduce cancer risk.
- On August 22 Michael West asked whether a short reprogramming signal would suffice to restore large damaged tissue.
- Magalhães added safety condition: returning regenerative ability could weaken tumor protection.
- Partial reprogramming temporarily returns adult cell to a younger gene expression mode while preserving specialization.
- To repair damaged tissue, cells need to divide and build new structure.
- This growth simultaneously requires control: uncontrolled division forms tumor.
- In the post, which references an article in Nature Reviews Cancer, Magalhães formulated hypothesis: "One of the reasons why developmental transitions limit regenerative capacity is, as I suppose, to reduce cancer risk."
- By this evolutionary hypothesis, natural selection could have preserved mechanisms that reduced cancer risk in young organism.
- These same mechanisms stop dangerous cell division and after tissue damage may restrain its regeneration.
- Two animal experiments show such conflict in specific systems.
- In a 2010 study on mice, the MRL line, which has good ear-hole regeneration, ear connective tissue cells lacked p21 — a protein involved in division arrest.
- Mice lacking p21 closed ear holes similarly to MRL.
- In a 2015 study on zebrafish, scientists introduced human ARF gene into genome, which helps suppress tumor growth.
- After fin amputation, ARF activated in blastema — a mass of dividing cells from which the fin regrows.
- In a separate experiment, temporary activation of ARF inhibited regeneration via p53, the cell division control system.
- With partial reprogramming, one must simultaneously check whether the intervention restores tissue's regenerative ability and whether cell division control is preserved.

We need to wrap key numbers, percentages, drug/company/gene names, dates in .

Key facts: dates: August 27, August 22, 2010, 2015. Gene names: p21, ARF, p53. Possibly also MRL line (mouse strain). Also "Nature Reviews Cancer". Also maybe "Michael West". Also "João Pedro de Magalhães". But we need at most 4-5 double asterisks. So we need to be selective: maybe only the most important: dates (2010, 2015) and gene names (p21, ARF, p53) maybe also August dates? But we can only have 4-5. Let's decide: we can include 2010, 2015, p21, ARF, p53. That's 5. Or we could include August dates but they are less critical. We'll go with those.…

LessWrong user links egg freezing to family planning decisions

On 26 August, LessWrong user boba_girl wrote a note following the June Reproductive Frontiers conference, linking egg and embryo freezing to family‑size planning. She views oocyte cryopreservation, embryo creation, and polygenic screening as interconnected decisions about timing, partner choice, and the number of possible births.

She starts from her personal situation: she wants children but is still looking for a partner. “I think that once I find a partner I will also try to freeze some embryos,” she writes. Until then, storing eggs buys her time to choose a partner.

Embryos are created after a partner appears, and their number helps the family envision how many birth attempts they could plan. Thus, her reasoning links the choice between eggs and embryos to two goals: preserving freedom to choose a partner and anticipating the possible embryo stock.

On the consumer market for polygenic screening, the procedure looks like a series of IVF cycles, genetic testing, and selection. boba_girl starts this chain earlier, asking what options can be preserved before embryos exist. Polygenic ranking compares the resulting embryos using statistical forecasts of disease risk and certain complex traits derived from genetic data.

The number of viable embryos determines both the number of comparison options for that ranking and the number of potential birth attempts. In her note, reproductive technology enters family planning step‑by‑step: first freeze eggs, then decide with a partner about embryos, and finally choose among those that are obtained.
